RESIILIENT WHEEL@A z. i,

Application led'r February 16, 1923. Serial No. 619,423. i*

To all whom t may concer/nii Beit known that I, VINCENT a citizen of theUnited States,fresidingzv at Apache, inthe county of Caddo andnState ofOklahoma, have invented certain new and useful Improvements in aResilient V'Yheel, of which the following is a specificatiOIL'. l

This invention relates to wheels which are particularly adaptable forassociation with motor vehicles and the primaryobject of the inventionis to provide a wheel, which will have all of the advantages of a wheelequipped with a pneumatic tire, but none of the disadvantages thereof,such as blowouts, punctures andthe like.

Another object of the invention is` to provide a resilient wheelembodying an inner wheel member having a pneumatic ltire associatedtherewith and an outer wheel mem- 'oer res-ting upon and enclosing saidpneumatic tire, the outer wheel member having a wear treadsurface formedthereon for engaging the ground, thelinner and outer wheel members beingso associated, as to prevent the entrance of dust and dirt, into theinner wheel member.

.A further object of the invention lis to provide a resilient wheel, lformedrof sheet metal or the like, which will be of light weight, yetcapable of withstanding all shocks transmitted thereto.

A. further object of the invention is to provide novel means forconnecting the pneumatic tire with arim of the outer wheel member, so asto prevent the slipping between the inner wheel member and thel outerwheel member. l

A still further object of the invention is to provide an improvedresilient wheel of the above character, which'will be durable andefiicient in use, one which will be simple and easy to manufacture, andone which can beV placed upon the market ata reasonable cost.

With these and 'other objects vin view, the invent-ion consists inthenovel construction,

arrangement and formation of parts, as will be hereinafter morespecifically described, claimed, and illustrated in the accompanyingdrawings, forming a part of this speciflcation, in which drawings:

Figure 1 is a side elevation of the im-V proved resilient wheel, showmgparts there- A. WALKUP,

Figure 2 is an elevation ofthe inner wheel member. i n i i Figure 3V isa diametric section through the improved vresilient wheel,-Aillustrating the improved resilient wheel, illustrating the means ofassociating the same with asteer ing wheel spindle. y A Figure 4 is anenlarged'. fragmentary ysection through the periphery of the'improvedresilient wheel.

VINCENT A. WALKUP, or HACHE, 'oKLAHoMm if Referring to the drawings findetail,

wherein similar reference characters designate kcorresponding partsthroughout the several views the letter A. generally-indicates theimprovedv resilient wheel, which yincludes the inner wheel memberB, andthe outer wheel member C. A

The inner wheel member B comprises a pair of -concavo-convex shapeddisks 5 and G, which are connected together adj acentto their outer endsb-y means of bolts or the like 7. The. inner portion ornaXial center ofvthese disks 5 and 6 are provided y with openings for receiving the huband rthese disks are supported Aor otherwise secured, as at Sitoannularhub flanges y9. The pevripheries of the disks 5 and 6y areprovidedwith integral outwardly extendingibowed flanges 10 and 11, whichconstitute arim for receiving any preferred type offpneumatic the typecommonly employed .on bicycle Vwheelsor may be of the typel commonly-used `on' automobile wheels. The periphery ofl rtire 12. This pneumatictire 12may beof the tire 12 howeveris provided .with radially form aseat for the pneumatic tire 12 `and an outer convex surface 22for'forming aseat for'the tread 23, which can be formed of 5 and. 6 andsolid rubber if so desired. The side edges of the rim 20 are providedwith outwardly extending annular flanges 2li for engaging the sides ofthe tread or'tire 23 to prevent displacement thereof. This rim 2O ispreferably formed of met-a1 of light weight and of the desired thicknessand can be provided with one or more rows of openings25 for receivingthe drive lugs 13 on the pneumatic tire 12.

Now the inner surface of the rim 2O has secured thereto on each side ofthe inner wheel member B and in spaced relation' thereto flatdisk-shaped guard plates 30 and are provided with relatively largeopenings 32 for permitting the passage of the hub of the inner wheelfree movement of the hub member o-r free movement of thei rim 20 and theplates 30 and '31 in relation to said hub member. As clearly shown inFigure 3 of the drawings the disk plates 30 and 31 are provided atspaced points with outwardly extending attaching lugs 33 which can bebolted or riveted as at 34 to said rim 20.` It is preferred however tohave one of the plates 30 or 31 freely removable in order to permitaccess to be readily had to the inner wheel member B. v

In order to prevent the entrance of dust, dirt and the like into theouter wheel member suitable flexible disks, formed of rubberjor the like35 are placed against the outer faces of the disk plates 30 and 31 andthese flexible plates 35 snugly engage the hu' A'suitable inflationvalve 36 is provided member therethrough. i These relatively largeopenings 32 permit use of a pneumatic tire, without any dis-f.

advantages heretofore inherent with the use thereof.

From the construction of the outer wheel member C the entrance of rainorthe like in said wheel member is effectively prevented, whereby thepneumatic cushioning member 12 is ful-ly protected from the elements.31. The axial centers of the disks 30 and 31 i Changes in details may bemade without departing from the spirit or the scope of this invention.

What I claim asnew is z As a new article of manufact-ure va re-` silientwheel comprising an yinner wheel 'f member including a hub having spacedannular flanges formed thereon, concavo-conver shaped disks securedl tothe inner surfaces of said flanges, an'integral rim formed on theperiphery of said disks, a pneumatic cushioning member connected to saidrim, an outer wheel member including a rim having a seat formed` on theinner surface thereof for receiving the cushioning member, said seatbeing provided with spaced openings, a seat formed on the periphery ofthe rim of the outer wheel member,- a tread fitted in said lastmentioned seat, driving lugs formed on the cushioningl member fitted insaid openings in the inner seat, guard disks secured to the rim of theouter wheel member arrangedv on each side of the disks of the innerwheel member, and fiexil ble disks securedv to the hub of the innerlwheel member and contacting the outer surface of the guard disks of theouter wheel member.

In testimony whereof I affix my signature in presence of two witnesses.
